Achromic Apeirons
Slivers of the Void Aspect
One of the most ubiquitous Slivers to exist, this solid/liquid/gaseous/plasmic substance makes up a significant part of the Furthest Ring, and thus all of existence. It is, as its name suggests, completely colorless. Such that it is actually invisible to normal senses. Even to touch. The only way to detect the substance is either by having something color it somehow, or through Void attuned senses.
The Apeiron react violently when exposed to even the slightest bit of Certainty, mostly introduced through the Light Antergy, the Apeiron collapse their uncertain nature into other, knowable substances. In nature, this mostly means that the Apeiron transmute themselves into a cloud of random quarks and disperse into the ether. Never to return again. They do occasionally change in concert, allowing random masses of objects to come in and out of existence in the Furthest Ring whenever you blink in there. It’s very unnerving to witness. Large amounts of Apeiron transmuting spontaneously is usually the preamble for the emergence of a new Session.
Sublimation
Apeirons transmute themselves when introduced to Certainty, they likewise return when all Certainty leaves them. Terrible koans aside, Apeirons are essentially the building blocks of most matter in a Session and the Furthest Ring (and probably the Universes as well, but that's still just conjecturing at this point) and building blocks can come back if the Building is taken down.
As all Timelines of a Session exist simultaneously in the Furthest Ring, Doomed Timelines all come into existence along with any Stable Timelines. As far as things can exist in the Furthest Ring anyway. When Doomed Timelines reach their Game Over point, all matter in the failed Session is slowly converted back into Apeiron. To make ‘room’ for ‘future’ Sessions to be created.
Apeirons can also sometimes exist in Void Player Lands. Though that usually means that the Land and/or Session is slowly deleting itself due to some error in construction. So The Player better figures out a way to stop it quickly.
Alchemy
Achromic Apeirons can be alchemized using a combination of any three Void-bound Grist type. It can also be created by inputting Perfectly Generic Objects in an Antergy Sublimator and adding Void Antergy. Just make sure it doesn’t collapse its non-existence in its container. Apeirons are some of the hardest substances to contain because of how often it happens.
Items cannot generally incorporate Apeirons into their design, not unless a Void-bound is manning the Alchemizer. Stranger things have happened in Sburb however, so its possible that others can find a way to get in on the action as well.
Items that incorporate Apeirons are usually those that can have semi-stabilized its existence. This results in shapeshifting items that can modify its composition. Certain items can also convert things to and from the Apeiron phase. This is usually the realms of invisibility cloaks, disintegration rays/swords, and transmutation equipment.
Powers
Powers based on Apeirons are quite similar to those items that are made of or manipulate it. They can usually collapse nearby matter into Apeirons, effectively disintegrating them. Others can grab Apeirons out of the void and shape it to their user’s will. Essentially an elemental path to the standard Create/Destroy Nothingness power most void users seem to get these days.
